Introduction and Welcome
Dear Colleagues,
On behalf of the Conference Planning Committee, we invite you to peruse this proceeding of the international conference: GEOBIA 2008 - Pixels, Objects, Intelligence: GEOgraphic Object-Based Image Analysis for the 21St Century. Please note that only full proceedings papers have been included in this document. GEOBIA, 2008 was held at the University of Calgary, Alberta, Canada August, 5-8, 2008. A total of 137 participants from 19 different countries attended the conference and 8 workshops over the 4-day period that featured 3 keynote addresses, more than 63 regular oral presentations in three concurrent sessions, poster sessions and a student prize award for best paper. A special joint session titled 'GEOBIA in Support of Government of Canada Needs' was also held. GEOBIA, 2008 was co-organized in partnership with the Canadian Space Agency, the ASPRS and the ISPRS. A GEOBIA special issue of Photogrammetric Engineering and Remote Sensing (PE&RS) will be published in 2009.
GEOBIA (pronounced ge-o-be-uh) is a recent sub-discipline of Geographic Information Science devoted to developing automated methods to partition remote sensing (RS) images into meaningful image-objects, and assessing their characteristics through spatial, spectral and temporal scales. Its applications range from agriculture and natural resource management, to national defense and global climate change. Its economic impact spans from data collection, hardware and software vendors, developers and users, to recipients of sound sustainable environmental policy.
GEOBIA 2008 builds upon the success of the 1st International Conference on Object Based Image Analysis (OBIA 2006), held in Salzburg Austria, where over 120 participants from 24 different countries attended to discuss the latest advances in this developing field. An edited book1 has been published from extended peer-reviewed conference papers. A GEOBIA Wiki2 has also been established to facilitate community interaction related to this conference.
A key objective of this event was to facilitate a forum for this growing international community of practice from which we can better share in the latest developments of GEOBIA theory, methods, and applications so as to more intelligently exploit remote sensing imagery. Our theme - 'Pixels, Image-objects, Intelligence: GEOgraphic Object-Based Image Analysis for the 21st Century' - is intended to highlight this objective, and the evolution of this discipline.
We invite you to help build this discipline by contributing your comments, expertise and experience at GEOBIA, 2010, to the GEOBIA Wiki and to the newly proposed GEOBIA.org website.

Keynote Abstracts:
GEOGRAPHIC OBJECT-BASED IMAGE ANALYSIS (GEOBIA) IN CONTEXT: PAST, PRESENT AND FUTURE. Geoffrey J. Hay, University of Calgary
What is Geographic Object-Based Image Analysis (GEOBIA)? To answer this we provide a historical, geographical and contextual overview leading up to this conference. We then propose a formal definition of GEOBIA along with a brief account of its coining and recommend a key objective for this new discipline. We then, propose GEOBIA’s main tenets and discuss its plausible future. Much remains to be accomplished.
10 YEARS OF OBJECT-ORIENTED IMAGE ANALYSIS FOR GEOSPATIAL APPLICATIONS: EVOLUTION AND OUTLOOK. Martin Baatz, Gregor Willhauck, Christian Hoffmann. Definiens
Automated feature extraction from earth observation data is a key requirement in numerous application fields. Increased availability of remote sensing data and increasing market request generate a demand for high-throughput information extraction. Spectral variation, level of detail and the multitude of forms of appearance of specific types of landcover features however are only some aspects that set significant challenges for fully automated analysis. Object-based and object-oriented image analyses have proven in recent years to be a new paradigm for automated feature extraction. At the same time, a shift in focus from desktop based interactive workflows to industrial production workflows can be observed. This contribution discusses requirements and challenges within this context. In order to support fully automated processing, semantic segmentation approaches are needed that are knowledge-based as well as context-driven and support modelling at the same time. Fast adaptation to new tasks, scalability and integratability are further key requirements. An overview about the evolution of Definiens object-oriented Cognition Network Technology is combined with an outlook on future trends and developments.
AUTOMATED FEATURE EXTRACTION FROM TERRESTRIAL AND AIRBORNE LIDAR. Stuart Blundell, David W. Opitz, Raj Rao Visual Learning Systems, Inc.
The U.S. Army and other Department of Defense (DoD) combat and combat support agencies requires automated feature extraction (AFE) software for collecting very high-resolution 3D urban features from terrestrial LIDAR data to support the ground-based Warfighter operating in the urban battlespace. Advanced vehicle-mounted and man-portable terrestrial Light Imaging and Range Detection (LIDAR) systems capture accurate 3D measurements of the urban environment with spatial resolutions on the order of 5 centimeters or less [Blais, 2004]. The 3D imaging capability of these systems is negated, however, by a lack of commercial software tools capable of exploiting terrestrial LIDAR datasets [Shiode 2001]. Current approaches for creating high-resolution 3D urban models are expensive requiring thousands of man-hours to digitize feature geometries, assign textures to features and attribute features. The lack of robust AFE software tools for collecting geospecific urban features from terrestrial LIDAR systems directly impacts applications for facility reconnaissance, special operations planning and urban warfare decision-making. Visual Learning Systems, Inc. (VLS) has developed a IDAR AFE system capable of extracting over 1,000 buildings per minute as 3D Shapefiles from airborne LIDAR. In this presentation we provide an overview of the VLS solution for 3D AFE from advanced terrestrial LIDAR systems operating in urban environments.
